The Flora of Disko Island and Adjacent Coast of West Greenland. 33 
Sometimes it occurs in places that are inundated in the spring 
and early summer. In these places it develops long floating leaves 
and resembles the following species. 
During wet summers, when the pools do not dry up, it does not 
flower, thus differing from the following one. 
Because of its vegetative luxuriance in manured places it is par- 
ticularly adapted to fodder for sheep and goats, both as green fodder 
and as hay, and perhaps it may prove itself a valuable fodder-plant in 
subalpine regions. But there is an inconvenience by the hay-making: 
the plant forms big semispherical tufts which render the mowing with 
scythe difficult. The green turfs formed by its web of roots are very 
compact, hence preferred by the natives for house-building 
Very common on Disko and the Mainland around Disko-Bay; 
also common in the archipelago of Egedesminde district and south- 
wards along the coast down to Holsteimsborg. 
Still frequently to be found at the tent places in the fjords, but 
else very rare here or quite absent. 
Possibly it may be found isolated in alpine habitats; we did not 
find it during any of our excursions on the hills although we searched 
for it. 
In N. Stromfjord it was very common on the islet Taseralik at 
the mouth of the fjord, where yearly 3—400 men and women meet; 
at the tent- and fishing-place Eqaluarssuit it was found in great abun- 
dance, but locally; but not at any of the tentplaces within that, 
not even in the hills. 
In the region of Holsteinsborg it has been found a few times in the 
vicinity of Amerdloq-Fjord down to 66°45’ and for the present this 
place must be etablished as the south limit of its continual distribution. 
It has been recorded isolated from the head of Kangerdluarssuk-Fjord 
at Frederikshaab by Tu. Hotm (Enciers Jahrbiicher VIII, p. 200), 
but the specimen does not exist. Mistake of identity is excluded; per- 
haps it was alpine here, but this is not recorded by the collector. 
Northern type; in East Greenland known to ca. 68°, but does 
not occur on Iceland (yet in Scottish mountains). 
Ascends, following the bog-formation, to the snow-line. 
Abundantly flowermg and fruiting. 
Hibernates covered by snow. 
A 31. Alopecurus aristulatus Micux. 
Rooted in small ponds and on lake-shores with floating leaves and 
stalks. During exceptionally dry summers to be found trailing on the 
LVITI. 3
